Summary:Calculation of the basic kinetic parameters of thermo-oxidative destruction of initial, porous HDPE and copper-containing composites based on porous HDPE was carried out by the IKP method. It was shown that thermo-oxidation of these materials consisted of three stages: (1) the migration of oxygen molecules to the active oxidising centres and the beginning of chain oxidation; (2) destruction of polymer molecules; and (3) thermodegradation of “nuclei”. However, porous HDPE was oxidised at lower temperature. Thermooxidation of copper-containing porous HDPE composite was characterised by the higher activation energy.
